Decentralized microblogging software and network that lets communities run their own social servers.

Donation-funded nonprofit model; the 2024 annual report shows €2.2M total revenue, and Mastodon also announced a €614k Sovereign Tech Agency agreement in 2026.

Mastodon is free, open-source software for running federated microblogging servers that interoperate across the broader Fediverse. Users can join a server that matches their community norms or run their own, which prevents the platform logic from being captured by a single owner.

No ads or ranking algorithms; privacy depends on the server you join or host.
